The invention appertains to a sadiron heated by an alcohol burner and has for its general obliect to produce an improved heating unit that not only is simple of construction but also is economical of operation.

More particularly the invention aims to provide a safe and reliable generator and burner tube combined as a unit with the fuel storage tank. The parts are so associated that they are detachably mounted as a unit in the body of the sadiron.

A distinctive feature lies in the mode of mountn ing the unitary members and securing them in a detachable manner.

Th-e invention will be better understood by reference to the accompanying drawing in which Figure l isa side elevation of the sadiron.

Figure 2 isa rear elevation viewed on the line 2-2 looking in the direction of the arrows and depicting a locking plate in open position.

Figure 3 is a similar View but showin-g the locking plate in closed position.

Figure 4 is a lengthwise sectional View of the heating unit removed from the body.

Figure 5 is a fragmentary rear perspective view of the body showing a slot that forms part of the mounting for the heating unit.

Like numerals of reference indicate corresponding parts in each figure throughout the drawing.

In the embodiment of the invention herein illustrated, the body ii is of conventional shape, having a suitable handle 'l and the customary complement of passages 8 for admitting air and for allowing escape of the products of combustion.

The interior of the body constitutes a heating chamber 9.

The burner tube lil extends forwardly from the rear of the body and is perforated at each side to provide longitudinal series of holes as at Il for the ame jets.

The rear of the burner tube has a crook i2 from which the tube is upwardly continued at i3 and joined by a coupling nut ill to the valve l5, there being one or more vent openings i5 below the nut to admit air so as to form a combustible mixture forwardly of the valve.

The valve has a passage Il communicating with a generating chamber it and controlled by the needle valve I9 that upwardly extends from the top of the valve. A horizontal wick tube eX- tends rearwardly from the valve and is connected by a coupling nut 2t to the fuel tank 2l. The Wick 22 extends into the tank to draw up the liquid fuel and to convey it to the generating chamber.

(Cl. 15S-23.2)

To start the burner in operation, external heat is applied by a pilot or other knwn means to vaporize the volatile fuel in the generating chamber. The gas flows down the burner tube, commingles with air admitted by the perforated part i3 and burns injets emanating from the holes i i.

The burner tube, valve and tank are referred to as a unitary heating unit. The mode of detachably mounting this unit in the body comprises the provision of the slot 2t extending inwardly from the top of the rear face 2d of the body. The valve is supplied with a pair of spaced flanges 25 at each side so as to define respective intervening recesses. Therecessed portion of the valve is in serted in the slot 23 so that the flanges shoulder it on the body and thus mount the heating unit in proper position.

To secure the heating unit in position, a locking plate 26 is employed, which plate is disposed adjoining the rear face 2li and pivoted at 25 to one side of the body for swinging movement in a transverse plane, foi` which purpose a knob 2d is supplied. The locking plate rests on a shoulder 2l' and has an arcuate slot 2B extending upwardly from itsbottom edgeand curved substantially on a radius whose centre is coincident with the pivot 25 so as to clear the wick tube. The plate blocks the valve in its closed position. The locking plate carries a closure plate Z9 pivoted at Bil and adapted to lie across the slot 26. Said closure plate has vent passages 3l.

What I claim is:

1. In a sadiron, an elongated chambered body open at the rear end, said rear end terminating abruptly in an end face, said rear end including a top wall having a slot extending inwardly from said end face, a unitary heating unit including a valve having a horizontal tube extending therefrom, said valve having a pair of spaced flanges on each side dening recesses by which the valve is insertedV in the aforesaid slot, and a locking plate 'pivoted to the end face aforesaid and adapted to transversely swing over the horizontal tube to retain the valve in place, said locking plate having an arcuate slot receptive to the horiI zontal tube.

2. In a sadiron, an elongated chambered body open at the rear end, said rear end terminating abruptly in an end face, said rear end including a top wall having a slot extending inwardly from said end face, a unitary heating unit including a valve having a pair of spaced flanges on each side defining recesses by which the valve is inserted in the aforesaid slot, and a locking plate pivoted to the end face aforesaid so as to swing into engagement with the valve to retain it in the slot. side defining recesses by which the Valve is 'in- 3. In a sadiron, an elongated chambered body serte in the aforesaid slot, and a locking plate open at the rear end, said rear end terminating pivoted to the body laterally of the valve, said abruptly in an end face, said rear endincluding a locking plate having an arcuate slotted portion top Wall having a slot extending inwardly from adapted to t over the Valve to retain it against f5 5 said end face, a unitary heating unit including a displacement,
